How to Bleed Motorcycle Brakes from Empty
Bleeding motorcycle brakes from an empty reservoir can be a daunting task for many riders, but it is a necessary procedure to ensure the proper functioning of your braking system. This article will guide you through the steps of how to bleed motorcycle brakes from empty, ensuring that your brakes are both safe and effective.
1. Gather the Necessary Tools and Materials
Before you begin, make sure you have all the necessary tools and materials. You will need a bleed kit, which typically includes a syringe, brake fluid, and a bleed nipple tool. Additionally, you’ll need a clean rag, gloves, and a flat, stable surface to work on.
2. Park on a Level Surface and Set the Parking Brake
Park your motorcycle on a level surface and apply the parking brake to prevent it from rolling. This will ensure that the bike remains stationary during the bleeding process.
3. Remove the Reservoir Cap and Bleed Nipple
Locate the brake fluid reservoir on your motorcycle and remove the cap. You will also need to remove the bleed nipple, which is typically located on the caliper or master cylinder. This can usually be done by unscrewing it with your fingers or a small wrench.
4. Attach the Syringe to the Bleed Nipple
Attach the syringe from your bleed kit to the bleed nipple. Make sure it is securely fastened and that the plunger is fully extended.
5. Prime the System
With the syringe attached, pull the plunger back to create a vacuum in the syringe. This will draw brake fluid into the syringe. Once you have enough fluid, push the plunger back down to expel any air bubbles and ensure that the system is primed.
6. Bleed the Brakes
Now, it’s time to bleed the brakes. Have an assistant press the brake lever or pedal while you pull the plunger on the syringe. This will allow brake fluid to flow through the system and out of the bleed nipple. Continue this process until the fluid coming out of the nipple is clear and free of air bubbles.
7. Reattach the Reservoir Cap and Bleed Nipple
Once the brakes are bled, reattach the reservoir cap and bleed nipple. Make sure they are securely fastened to prevent any leaks.
8. Check the Brake Fluid Level
Check the brake fluid level in the reservoir and top it off if necessary. Be sure to use the correct type of brake fluid for your motorcycle.
9. Test the Brakes
Before riding, test the brakes to ensure they are functioning properly. Apply the brakes several times to help expel any remaining air bubbles.
By following these steps, you can successfully bleed your motorcycle brakes from empty. Remember that proper maintenance of your braking system is crucial for your safety on the road. If you’re unsure about any of the steps or if you encounter any issues, it’s always best to consult a professional mechanic.
